The aim of this study was to verify relation between kinematic variables of temporal-spatial parameters and manual ability and between own temporal-spatial variables during the movement of bring a mug to the mouth in adults with dyskinetic cerebral palsy (DCP). Sixteen adults with DCP were evaluated by MACS (Manual Ability Classification System), and by temporal-spatial variables of tridimensional kinematics of the movement to bring a bug to the mouth by means of 9 cameras infra-red Vicon(r) MX 40 (Oxford Metrics Group, Oxford, UK). The Spearman correlation coefficient (ρ) was used to correlate variables. As a result, we found weak correlation between the classification of manual ability and the adjusting phase (ρ=0.219), the velocity variables - average velocity (ρ=-0.313), peak velocity (ρ=-0.282) and time to peak velocity (ρ=-0.250). No correlation was found between the variables going and returning phase and MACS. Moderate correlation was found between going and returning phase (ρ=0.559), between the going phase and time to peak velocity (ρ=0.518) and between the adjusting phase and peak velocity (ρ=-0.562). A strong correlation was found between the mean velocity and peak velocity (ρ=0.947) and between the adjusting phase and average velocity (ρ=-0.635). In conclusion, functional impairment may be related to longer adjusting phase and decrease of movement speed in subjects with PCD. Kinematic variables were related to each other in moderate and strong way and indicated that the phases runtime influences the movement speed.
